Migration File

$table->increments('id');
$table->foreign('user_id')->references('id')->on('users');
$table->foreign('band_id')->references('id')->on('bands');
$table->foreign('genre_id')->references('id')->on('genres');
$table->foreign('cate_id')->references('id')->on('cates');
$table->foreign('type_id')->references('id')->on('types');
$table->integer('status');
$table->date('date');
$table->time('time');
$table->decimal('price');
$table->tinyIncrements('instrument');
$table->string('instrument_detail',255);
$table->timestamps();

After run php artisan migrate

The next sentence:

$table->foreign('user_id')->references('id')->on('users');

just tells the db to make a link between the parent/foreign columns, but in order to do it the column must previously exist, so:

$table->unsignedInteger('user_id'); // first this
$table->foreign('user_id')->references('id')->on('users'); // then this

You should do this for every foreign key.

Note:

Laravel doens't need you to define this links because it doens't make use of this, is just for database consistency sake.
